The Amazing Benefits of Valerian Root for Better Sleep

Both physiological and psychological health depends on a good night’s sleep.

Appropriate sleep helps the body refresh and allows the brain to get ready for the upcoming day.

When a person fails to sleep enough, they start to experience signs of sleep deficiency. This can cause problems with their mental health, increasing the risk of anxiety, depression, and similar issues.

The physical health of the body suffers, too, increasing the risk of obesity, heart disease, and more.

The average adult needs between seven and eight hours of sleep each night1. According to the Centers for Disease Control and Prevention, an estimated 35.2% of adults fail to obtain enough sleep on a daily basis2.

People with sleep disorders have several options to consider. It is possible to take certain pharmaceutical drugs to improve sleep. These drugs do come with some side-effects3. There are several alternative options available too.

Valerian root is an excellent example. This is a 100% natural plant extract that may help a person enjoy a restful sleep.

Health Benefits Of Valerian Root

Valerian root, also known as Valeriana officinalis, is often recommended for people who struggle with poor sleep. This is a herb that is known to possess medicinal properties.

The chemicals found in the valerian root may help with certain mental conditions. There are also suggestions that these chemicals may have a positive effect on a person’s sleep quality.

People interested in this natural sleep aid should understand what exactly the valerian root is. It is also essential to understand what the herb will do in the human body.

What Is Valerian Root?

Valerian is a plant that is native to regions of Asia and Europe. Even though native to these areas, valerian root is often grown in other countries too, including the United States.

This is a type of flowering plant. It grows above the ground and will generally have a height of about 1.5 meters when mature. The flowers of the valerian plant will usually be either white or pink. These flowers give off a sweet smell. The valerian plant is also known for attracting a variety of fly species, including Eristalis hoverflies.

The root of the valerian flowering plant is used for its potential medicinal properties. Dried valerian root is used in a formula where dietary supplements are produced. In some cases, the root is also processed and used in a tea product.

The evidence regarding the valerian root is mixed. Many people seem to believe in the potential of this plant. At the same time, there are some concerns regarding the safety of the plant root extract.

Valerian root will often be combined with other herbal supplements and natural health remedies. Valerian and hops are an especially common combination in products that aims to help people struggling with insomnia4. Lemon balm is also sometimes added to these formulas to help calm the mind and body of the user.

What Are The Effects Of Valerian Root On The Body?

There are many chemicals found in the root of a valerian plant. These are the chemicals of interest when looking at the potential benefits of this herbal product.

Two of the most important chemicals of interested in valerian root include:

  • Isovaleric acid

  • Valeric acid

In addition to these two chemicals, there are also different antioxidants to be found in the root of a valerian plant.

The most important interaction would be with gamma-aminobutyric acid. Also known as GABA, this is a crucial chemical messenger in the body. GABA is involved in the regulation of nerve impulses that affect both the central nervous system and the brain.

The interaction between valerian root chemicals and GABA is what causes the sedative effects of the plant.

Previous studies have linked stress and low levels of GABA5. When GABA levels are too low, it seems to contribute to the development of insomnia. Sleep quality is also adversely affected by low levels of GABA chemical messengers. Furthermore, there also appears to be a higher risk of anxiety in people with a low GABA level.

The valeric acid may help to reduce GABA breakdown in a person’s brain. This means a person is likely to avoid those low GABA levels, especially during times of stress.

This process helps to provide a feeling of tranquillity. The individual may feel calmer when the breakdown of GABA is inhibited. Pharmaceutical drugs such as Xanax and Valium works similarly as the valerenic acid that is found in valerian root.

There are two specific antioxidants in valerian root that may further enhance sleep quality. These two include:

  • Linarin

  • Hesperidin

Both of these have been shown to possess sedative properties. The sedative action may help to improve a person’s sleep6.

The effects of valerian root in the body should be considered. It is also important to consider additional factors when valerian is mixed with lemon balm and other ingredients.

Individuals who have existing conditions that affect their liver need to be cautious. It is a good idea to speak to a physician before taking valerian in this case.

The physician will be able to determine if valerian root extract may have an adverse action on liver disease. The doctor will also help the patient understand if taking valerian dietary supplements may be a good and safe option for them.

When taking too much of the supplement, more serious side-effects could occur. This is why people need to ensure they comply with appropriate dosage recommendations.

Even though studies do seem to differ, there is a general range in which the doses of valerian usually falls.

It seems like valerian is most effective when taken at least 30 minutes before going to bed. The supplement may not be effective when taken too far away from bedtime. A maximum time of two hours before bedtime should be allowed.

Doses generally range from 400mg to 900mg when using valerian root as a way to sleep better at night. The use of a higher dose does seem to cause more side-effects or at least increase the risk of side-effects. These side-effects have been noted among people who use a 900mg valerian root supplement.
